Patented Feb. 3, 1931 UNITED STATES PATENT OFFICE HARRISON STBICKLER, OFERIE, PENNSYLVANIA, ASSIGNOR TO THE PBOTANE COR- PORATION, OF ERIE,PENNSYLVANIA, A CORPORATION OF DELAWARE VALVE MECHANISM FOER BURNERSApplication filed March 7, 1927. Serial No. 173,351;

' Burners operating upon fuel delivered to the burneras a vapor butconveyed'to the burner in the form of a liquid have some very seriousproblems as to control. If the closure mechanisms are remote from theburner a comparatively large volume of volatile liquid is'left betweenthe burner and the valve upon the closure of the valve which graduallyis vaporized and escapes to the room. \Vhere it has been attempted toplace the valve adjacent to the burner with the expansion of the partsincident to the heat of the burner difiiculty has been experienced inmaintaining the valve in working condition. By the present inventionthese difficulties are obviated and the valve so placed that verylittle, if any, liquid remains beyond the closure of the valve upon theclosure of the valve. The invention further contemplates the mounting ofthe valve and the metering devices in a detachable portion so that inservicing a ready change may be made of this critical part without aremoval of the main connections leading to the burner. A further featureof the invention contemplates the delivery of the fuel to the hotterparts of the apparatus in such a manner as to prevent the formation ofcarbon at the vaporizing point. Other features and details of theinvention will appear more fully from the specification and claims.

The invention is illustrated in the accompanying drawings as followsFig. 1 shows a section through the valve control means.

1 marks the stove frame, 2 the burner, and 3 the vapor expansionchamber. These are of ordinary construction. Liquid fuel is suppliedthrough a supply pipe 1. This pipe leads into a fitting 5 A supply tube6 extends from the fitting 5 forwardly to approxi mately the location ofthe burner. This may be longer or shorter depending on the location ofthe burner. A sleeve-shaped valve body 7 is detachably secured by screwthreads The ready removal of the 8 at the inner end of the tube 6. Thesleeve of this body is internally screw-threaded at 9 and a valve plug10 is screwed into this sleeve. The valve plug carries an extension 11with a ValXB head 12 at the end of the extension. The valve 12operatesupon a seat 13 in the body 7 and forms a closure means for themechanism. A meterpin extension 14 proj ects from the valve head andcarries a metering pin 15. The metering pin extends through a meteredopening 16 in the meter cap 17 An operating stem 18 has a squared end18a operating in a squared socket 19 in the plug 10, thus forming a slipconnection between the operating stem 18 and the plug 10. This slidingconnection as clearly shown in the drawings has a very loose fit forminga.

universal oint permitting the valve to remain concentric with the valvebody without binding of the parts, or injuring the seating surfaces.The. stem extends through a stuffing box 20 on the fitting 5 and isprovided with an operating handle 21.

The plug 10 has fuel passages 22. These are directed outwardly so thatthe fuel issuing from them strikes the hot walls of the body 7, thisbody being sufficiently close to the burner to receive heat from theburner.

In operation the stem 18 is turned and this operating on the plug andthrough the action of the screw opens and closes the valve and operatesthe metering pin to the position desired. The small jet passages 22where the liquid is released to a large extent are removed from theheated surfaces and thus prevent the formation of carbon which is apt tooccur at this point.

operating parts involved in the closure valve and the metering pinpermit of an exchange of these critical parts in the servicing of thedevice. The slip joint permits of the expansion and contraction of thetube under heat without undue pressure on the valve.

In the usual construction the application of heat to the drying tubetends to warp this tube out of shape. Warping is also frequent- 1yproduced in the assembly of the device.

This warpage causes binding, or misalineand permits easy and efiectiveoperation of the valve plugll even in the most aggravated cases ofmisalinement. The slip joint permits the operating stem 18 to be lockedagainst axial movement. This facilitates the packing of this stem whichis an important feature as the gases, or liquids, used in .connectionwith this burner are very penetrating. What I claim as new is I 1. In avalve mechanism for burners, the combination of a burner; a supply-tube; an

internally screw-threaded valve body in heatreceiving relation to theburner and in advance of the supply tube; a valve actuating screw in thebody; a valve actuated by the screw; and an operating stem having auniversal connection with the screw, said con nection being adjacent tothe screw.

internallyscrew-threaded valve body in advance of the supply tube and inheat-receiving relation to the burner; a screw plug in the body, therebeing means permitting the passage of fuel past the screw plug; a valvecarried by the plug; and an operating stem extending from the plug andhaving a uni- Versal connection with the plug, said connection beingadjacent to the plu 3. In a valve mechanism for internallyscrew-threaded body in advance of the supply tube and in heat-receivingrelation to the burner; a screw plug in the body having a fuel passagetherethrough, said passage discharging outwardly against the walls ofthebody; a valve carried by the plug; and an operating stem extending fromthe plug.
